To all who/m 'it may concern.'

Be it known that I, FRED l/I. KiLrorLE, a citizen of the United States, and a resident of Storrs, in the county of Carbon and State of Utah, have invented certain new and useful Improvements in Pulleys, of which the following is a description, reference being had to the accompanying drawing, which forms a part of my speciication.

My invention relates more particularly to a. clothes line reel or pulley of such construction that an endless clothes line may be disposed about a pair of reels or pulleys arranged a suitable distance apart, to permit the use of both strands or bights of the line and enable clothes to be suspended from or hung on the line at one end thereof and the line with the suspended clothes made to travel or pass about the diferent, separated pulleys. In other Words, my invention permits the clothes to be secured on the line at any suitable or selected point and the line gradually advanced a sufficient distance to permit a number of separate garments to be successively suspended therefrom, without requiring the yuser to Walk from place to place or to opposite ends of the line.

A purpose of my invention is to provide pulleys which will be comparatively light in construction; which may be' readily as sembled and dissociated or knocked down for shipmentg and Which at the same time possess the 'necessary strength and rigidity, While at thesame time of such construction that it Will be comparatively inexpensive in manufacture and permit of such mounting that any slack in the line may be readily taken care of and yet at the same time preventing thel line from readily slipping oil' the pulley or reel; the construction of the reel permitting the line With the clothes sus pended therefrom vto pass about the pulley or reel, Without, however, causingkgeneral Contact between the clothes and the pulleys or reels.

The objects and advantages'of my invention will all ybe more fully comprehended from the detailed description of the drawing wherein Figure 1 illustrates, in elevation, my improved pulley or reel supported from a suitable bracket, with a. portion of the line or Wire shown in place.

i Figure 2 is a sectional view taken on the line 2-2 of Figure 1. n

Figure 3 is a top plan View thereof.

Figure 1 is a perspective View of the outer hub member.

Figure 5 is a perspective view of the inner hub member. l

.In the particular exemplification of the invention as disclosed in the drawing, the pulley or reel. comprises a hub member or shell of metal or any suitable material;

`the opposite ends thereof being preferably 'provided with a number of sockets 10y for .the reception of the'spoke-forming Wires 11,

11, the inner ends vwhereof are adapted to extend into and be disposed along the inner surface of the shell or hub member 10. The yhub member or shell 10, at an intermediate point, is provided with a series of circumferentially arranged holes 10b, through Which the immediate ends of the Wires are disposed; the Wires, leading from opposite ends ofthe hub, being bent into parallel relation and passed through the holes as shown at 12 in Figure 2.

The inner ends of the respective wires or spokes are maintained in place by means of an inner hub or member 13, which may be in the nature of a cylindrical core or shell, having its sides provided `with longitudinally disposed grooves 13, at points registering with the holes in the outer' shell or hub 10, adapted to receive the portions of the Wires, arranged Within the outer shell or hub, to maintain the wires or spokes Ain place. The-,inner hub member or shell is preferably shown cored to receive-zil suitable bolt 1d which is secured in a suitable manner to a block or member 15. The opposite sides of the hubs are 'preferably provided with suitable discs or flanges 16 karranged in pairs and grooved to provide race-Ways for the ball-bearings indicated at 17; the discs being shown held in place, at one end, by the bolt-head, While the discs at the opposite or upper end of the hubs are shown 'clothes to pass about the of a single wire bent to form the loops or extensions 19 and 20; the object being to provide the diverging loops or extensions 19 and 20 whereby a suitable crotch or groove is provided for the reception oit the line 18. I prefer that the extension or loop on one side of the reel or pulley, namely the side which is disposed downwardly, be made of slightly greater length than the eX- tension or loop 19 to prevent possibility of the line or wire slipping out of the crotch or groove and `therefore olf the reel.

The block or member 15 is preferably shown reduced or socketed on opposite sides to receive channel irons 21, 21 of a supporting bracket indicated atI 22 in Figure 1, which is adapted to be bolted or otherwise secured to any suitable upright or post as shown at 23 in ,Figure 1. The bracketl 22 may be in the nature of a metallic loop disposed about opposite sides ot' theblock or member 15; with the intermediate or outer portion ot the bracket preferably provided with a block 24 having a tapped opening for the passa-ge of an adjusting bolt 2lia of suitable length, so that when the bolt is screwed inwardly it will force the block or member 15 toward the inner end of rthe bracket 22 and thereby cause the pulley or reel to be moved toward the attached end of the bracket, namely in a direction away from the pulley or reel located at the opposite end of the line; the construction enabling any slack in the line to be taken up.

My improved pulley is more especially intended for use in connection with clothespins of the type whereby the clothes are suspended from and beneath the line without actual contact therewith; namely the type of clothes-pin disclosed in my prior Patent No. 1,398,969, December 6th, 1921. This type of clothes-pin enables thev clot-hes to be suspended yfrom the line a distance suflicient to clear the downwardly disposed loop or prongl 20 of the respective spokes, thus enabling the line with the suspended pulleys arranged at opposite ends of the lin 1 My present construction permits the use of the entire line, while the user is enabled to apply the clot-hes to the line from a.- given point or same position. without necessitating walking from end to end of t-he line to lill the; entire line; and where the line is suspended at a height from the ground, it is evident that the full length of the line may be employed and therefore a greater number of garments suspended from the line and its full capacity employed; and br merely ypresenting the prongs or forks to the line, instead of a rim or continuous periphery as in the ordinary pulley, it makes it possible for the clothes to pass about the pulley without contact therewith.

. The construction shown and described is comparatively light in weight, while at the same time possessing the required strength and rigidity; the spokes or wires being of any suitable non-rusting metal so as to withstand the elements and not be affected by moisture. It is also apparent that the pulleys may be operated by any suitable means, it desired, although they are readily operable by hand because of lightness in construction.

ln the preferred construction ot my invention, the spokes are preferably each composed rom a single wire; with the upper strand preferably made to extend substantially straight outward from the top end of the hub, as shown in Figure 2 and bent into the loop form as previously described; the wire or spoke is then twisted so as to provide a small loop or eyelet at a point just rearward of the line-receiving crotch as shown at 25, The spoke is preferably formed so as to have the lower strand .ot the wire extend in the downward inclining manner toward the lower end ot the hub, thus causing the lower strand to act as a brace ,tor the outer end of the spoke. The small loop or cycle-t 25 is intended to be just large enough to receive ar tie-wire 26, which is preferably employed to reenforce and maintain the spokes in spaced' relation. The small loop or eyelet is arranged at a point in the spoke, rearward of the line-receiving crotch, where the tie-wire 26 will not interfere with the line and there-tore not intertere with the tree passage of the clothes and the holding pins. I prefer to p-rovide the tie-wire 26 with small enlargements or lugs 27 arranged in pairs and spaced sutliciently apart to receive the spoke therebetween;v the enlargements being small enough, however, to enable them to be forced .through the small loops or eyelets Awhen it vis desi-,red .to thread the tie-wire therethrough in assembling the pulley. The ends of the tie-wire 26 are provided with a turn-buckle 28 where-by the tie-wire may be made taut. The arrangement ol the spokes as shown, with the tie-wire as described, greatly increases the strength of the spokes; the tiewire being placed under a tensile stress when the outer end ot the spoke receives a ydownward pressure; while the great angle or inclination of the lower strand of the spoke acts as a brace and therefore will sustain more strain.

As is apparent from the construction shown and described, a pulley or reel is provided which may be readily put together or assembled, while at the same time the pulley or reel may be quickly knocked down or taken apart upon removing the securing bolt from the inner hub member 1.3 and then withdrawing the inner hub member 13 from the outer hub or shell 10, which will permit the respective spokes to be removed from the hub 10 after releasing the tie-wire. knocked down pulley or reel to be stored in a comparatively small space or packed in a small carton for shipment; while at the same timeenabling the parts to be easily assembled Without special skill or tools.

I have shown and described what I believe to be the simplest embodiment of my invention; having described the same in terms employed merely as terms of description and not as terms of limitation, as structural modifications are possible and may be made Without, however, departing from the spirit of my invention.
